现在我有以下环境：



具体配置如下：

PC1: 10.1.1.3/24
Router1's Eth0: 10.1.1.1/24
Router1's Serial0:192.168.1.1/24

PC2: 12.5.10.3/24
Router2's Eth0: 12.2.10.1/24
Router2's Serial0:192.168.1.2/24

下面是Router1的信息：

妈的，我又Ping不通了。。。。

你两个路由器网段都一样了，路由器1ping路由器2端机器A时会误以为A与自己同一网段，解决办法是设更为精确的路由~

OK，的确像你所说的那样，现在两台PC可以PING的通了，不过我又有新的疑问了：

1。如果PC1和PC2属于同一个VLAN，也就是说PC1和PC2必须在同一网段内，但是路由器1和路由器2的Ethernet0口又不能设置成同一网段。。。这是个问题
2。PC1属于VLAN10并且两台交换机都是1900系列，所以封装的TRUNK只支持ISL，那么在路由器1上的Ethernet口上如何设置ISL呢？（我设置了encapsulation ISL 10也不行）

RIP 在干吗？？？

sokillwhat

做路由选择啊

你帖配置？
